Why Should We Pray or Meditate?

So, if the universe is all knowing, why do we have to pray or meditate to seek guidance. Shouldn't it just give us what we need without us putting any effort in. I see your point but, I don't think that's going to get you very far in your process.

Here's a question from r/spirituality:

Why do we need to ask the universe for help (i.e. pray)?

Which is what praying is, right? Does not the universe already know what we need? Why do we have to ask for it? (I have tremendous difficulty praying or even just asking the universe or spirits for help. Begging the universe for help feels so stupid, but I desperately need to do it. I need help with so many things...)
